The M20.3 flip moved ACPI namespace enumeration to the ring-3 acpi
service; the kernel now builds the namespace only for the \_S5 sleep
type. That left the kernel's AML-to-device helpers unreferenced.
Remove the dead cluster (wireAcpiDevices, mirrorDevices, applyHid,
setEisaHid, applyCrs, parseResourceTemplate, parseAddressSpace,
devicePresent, matchHostBridge, findPciNode, readAdr, isPciRootNode,
isPciRootHid, PciContext) and every AML-decoding helper it alone used
(eisaIdToStr, seg4, cstr, hexDigit, rd16, rd32, readN, readLE,
readIntObj, packageLength/PkgLen) plus their tests and the now-orphaned
acpi-ids import. The static-table path keeps checksumOk, fadt, readGas,
readCntRegister, and rd. Also tidies two stale comments.
